Performance of a Vehicle on Crawles on Irregular Land With Suspensions Equipped With Magnetorreological Shock Absorbers

The suspension system of a vehicle has the main objective of dampening the transmission of irregularities in the terrain to the chassis. This is necessary to preserve the vehicle's internal components and to ensure greater comfort for the occupants of the car. For that, several studies were carried out in the area, proposing modifications in the passive and active suspensions, resulting in a greater dynamic stability of the vehicle. In military vehicles, the importance of these studies grows as they have larger dimensions and a greater mass, making damping more difficult. Analyzing this damping will be the basis for analyzing of this paper. Whose main analysis tool will be the improvement in performance by replacing the traditional passive suspension by a magnetorhelogic active suspension. For this, a MATLAB / Simulink model will be used by means of a block diagram.
